i cannot get into safe mode. my pc starts an automatic repair, then doesnt launch an automatic repair file correctly and keeps looping.

Ok, lets create a new admin user and see if the issue persist from it.
Create the user, log off your current user profile.
log into the new admin user and see if windows defender is acting correct from it.

Download Defender control.
Disable defender reboot.
Re enable defender reboot.

From an elevated command prompt.

defender reboot left this virus and i dont want to risk running trojandownloader

 

[Malnutrition]

The file is safe, I assure you.

 

[Malnutrition]

That is what is known as a false positive. I have used that program on many machines, sordum has safe software.

I'd highly suggest that you run the Kaspersky tool after disabling Defender.

Make sure the .reg file you downloaded earlier is saved to your desktop.

Download Power Run
Unzip it to your desktop.
Open the folder.
Run power run x64
Click file .... Add file.
Under file location paste the following.
Do not include the word code!!

C:\Users\Joshua Wilson\Desktop\Windefend.reg

Then click run file.

You should be able to merge the registry file now.


Then please re-run the last FRST fix, to ensure correct permissions are set.
Try and launch FRST thru power run as well, if the fix fails.
